Explanation:

Hi,On December 20, 1910, New Zealand born physicist Ernest Rutherford made his seminal gold foil experiment which led to first insight about the nature of the inner structure of the atom and to the postulation of Rutherford‘s concept of the “nucleus“, his greatest contribution to physics.

The Electron Cloud Model was proposed by Erwin Schrodinger. Thanks to this model, electrons were no longer depicted as particles moving around a central nucleus in a fixed orbit.

The Bohr model shows that the electrons in atoms are in orbits of differing energy around the nucleus. He used the term energy levels to describe these orbits of differing energy.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
